Practice

Same pattern as Books read — a bar graph of five children. New numbers, new story. Try each one on paper, then check the working below — or watch it drawn out, the same way the problem above is.

Question 1

A bar graph shows the number of egg trays sold by a bakery over four days. The bakery sold 18 trays on Monday, 22 trays on Tuesday, 15 trays on Wednesday, and 25 trays on Thursday. What is the average number of trays sold per day?

Work it out on paper, then check below. ▶ See the working

Question 2

A bar graph shows the number of seashells collected by five friends at the beach. Ben collected 14, Zoe collected 9, Ravi collected 11, Tara collected 6, and Sam collected 10. What is the average number of seashells collected?

Work it out on paper, then check below. ▶ See the working

Question 3

A bar graph shows the amount donated by five market stalls to a charity drive. Stall A donated $12.50, Stall B donated $8.50, Stall C donated $15.00, Stall D donated $9.00, and Stall E donated $10.00. What is the average donation per stall?
